A Study of Friction Behavior of a Single Cylinder Gasoline Engine 2018-32-0078

In order to improve the performance, fuel economy and future emission norms of a reciprocating engine, it is important to reduce the overall engine frictional losses. In this paper, author conducts an experimental study on the friction characteristics due to pumping loss, valve-train system, piston assembly, auxiliaries and transmission for a 110cc, single cylinder 4-stroke gasoline engine using frictional strip-down analysis.
This paper deals with the friction performance results for the new concept piston skirt design called the unsymmetrical skirt for least piston skirt friction. Also, parameters like piston profile, oil film thickness optimized for least friction. The piston profile is arrived for optimum contact pattern with least piston slap noise. The modified engine reduced the engine friction by 10% in comparison to the base engine.
